Unique Characteristics of an OOSAD Project

• OOSAD projects use a more iterative design approach, such as prototyping or object-oriented analysis and design.

• During the OOSAD process, the system evolves incrementally over the life of the project.– A portion of the final system is constructed during each

iteration phase.

• Define the system as a set of components.– Object-oriented development projects are developed using

ongoing management and evolving system functionality.

• Complete hard problems first.– The focus and ordering of system components change over

the life of the project.


6


• Use iterations to manage the project.– The workflow of an iteration

• Don’t plan too much up front.– Planning estimation improves over time.

• How many and how long are iterations?– An OOSAD project typically has 6 to 9 iterations.


7


• Project activity focus changes over the life of a project.– As the project evolves, system functionality evolves.
